MECHANICAL MOVEMENT.

SPECIFICATION formingpart of Letters Patent No. 644,351, dated February 27, 1900. Application filed October 30, 1899 Serial No. 735,217. (No model.)

To (LZZ whom it may concern:

Be it known that 1, CHARLES F. J. Dnrnss, of Davenport, county of Scott, and State of Iowa, have invented a new and useful Improvement in Mechanical Movements; and I do declare that the following specification, taken in connection with the drawings making a part of the same, is a full, clear, and exact description thereof.

This invention relates to that class of mechanioal movements where a rotary reciprocating motion of one shaft is obtained by continuously revolving another or power shaft placed at right angles thereto in one direction, and is especially useful when used in the operation of a washing-machine, churn, or wherever it is desired to use a rotary agitating movement; and the invention consists of an improved gearing and other mechanism by which the rotary motion of the power-shaft is transformed into said reciprocating rotary motion of the other shaft placed at right angles thereto.

In the accompanying drawings, Figure 1 is a side view of myimproved mechanical movement mounted in a suitable frame. Fig. 2 is a front view of the same, showing the movable parts in one position; and Fig. 3 shows the same parts in a different position.

A represents the frame, which carries the operating parts.

B is the power-shaft, mounted in bearings in the frame A and adapted to be turned in one direction and to the outer end of which may be secured a fiy-wheel or crank for convenience in revolving it.

O is the crank-arm, one end of which is fixed to the inner end of said power-shaft B and having a pin' or bolt D fixed to its other end and projecting at right angles therefrom.

The power-shaft B, crank-arm O, and bolt D may, if desired, be cast in a single piece.

Upon the bolt D is loosely secured one end of a connecting-arm E. The other end of said arm is loosely connected to one end or corner of a segmental casting F, which segmental casting is provided with a core through its center and adapted to be mountedupon and to turn upon a short shaft or spindle Gr, projecting from and preferably a part of the frame A. This segmental casting is provided with beveled teeth or cogs on one of its sides and close to its periphery. These teeth are adapted to engage the teeth or cogs of a bev eled gear wheel or pinion H, secured to a shaft or rod LWhich shaft is mounted in bearings in the frame A, so as to revolve in said bearings.

To insure the engagement of the teeth of the segmental casting with those of the pinion and to prevent strain upon said casting, a lug J, projecting upwardly from the base of the frame A, may be provided.

This mechanism is adapted to be operated in the following manner: WVhen the parts are in the position shown in Figs. 1 and 2 and the shaft B is revolved toward the right, the arm E will exert a downward pressure against the segmental casting to which it is connected, and said segmental casting being mounted on the short shaft G will turn thereon, and the teeth on said casting F engaging the teeth on the pinion will of course turn said pinion and the shaft I, to which it is secured. When the segmental casting reaches the position shown in Fig. 3, the pressure of the arm E against it is released; but if the turning of the shaft B is continued the arm E will naturally be drawn upward and after moving but a short distance will begin to pull the end of the segmental casting to which its one end is secured upward with it, and the engagementof the teeth with those of the pinion will of course cause said pinion and shaft I to be reversed. Thus in one complete revolution of the powershaft B the shaftI is revolved first in one direction and then reversed and revolved in the opposite direction the same distance, the rotary reciprocating motion of said shaft I being thus obtained in a simple and efficient manner.

Having thus described my invention, I-

the purpose of imparting a reciprocating rotary motion to said pinion and the shaft to which it is secured.

2. A crank-shaft mounted to revolve in a suitable frame, a segmental casting provided with teeth or cogs on one of its sides and mounted to revolve upon a shaft or spindle;

an arm loosely connecting said segmental casting with said crank-shaft.

3. In a mechanical movement a crank-shaft mounted to revolve in bearings in a suitable frame, the segmental casting F provided With teeth on one of its sides and loosely mounted OHARLES F. J. DETERS.
